Generation of municipal solid waste (MSW) continues to rise, which leads to loss of resources and increased environmental risks. The conventional treatment of wastes such as open dumping and land filling cause environmental degradation. Since the major fraction of wastes generated in India is organic wastes, composting has emerged as one of the best methods for treatment of wastes. Composting, ...

Waste disposal is one of the pressing problems.Millions of tons of municipal solid waste, hazardous/industrial wastes and agricultural wastes are handled daily throughout municipal areas. Each municipality confronts great challenges in disposing of its wastes in an efficient, cost effective and environmentally safe manner.Landfills in metropolitan areas are becoming full, and new ones are more ...

electronic wastes (e-wastes) is the most rapidly growing segment of the municipal waste stream. e- wastes comprise 2-5 percent of municipal solid wastes, including many different electronic products. iran is the biggest consumer of electronic products in middle east. approximately, 1.2 million computers are assembled in iran every year. there are more than 40 million active cell phones in iran....

The management of municipal solid wastes (MSW) in Latin America is, and traditionally has been, a primary responsibility of local governments. In a large percentage of medium-size municipalities in the region, the management of MSW may use between 30% and 50% of the total municipal budget. The management of solid wastes is a complicated process that not only requires the proper selection and ap...

Composting is clearly reported as one of the most effective technique to transform organic wastes into an interesting resource, useful to improve soil characteristics and playing a potential role in reducing greenhouse gases, due to its high content in stable organic matter (Favoino and Hogg, 2008). However, its agronomical properties are dependent on several factors, which pollutant contents b...

1.0 Problem Statement The disposal of municipal solid wastes is one of the most serious problems facing Waste generation is on the increasing trend due to exponentially renders waste management as a significant problem. The solid waste generation (lb/capita/day) has been on increasing trend since 1980, with the curr New York State alone generates 8.4 million tons of municipal solid waste per ye...

Due to urbanization increasing, poor planning, lack of financial support and etc, it results in the poor state of municipal solid wastes management in most cities, especially in developing countries. A mass of solid wastes are dumped in the open air without effective environmental conservation measures, which leads to some open-air solid wastes dumps. Management of these dumps is one of the mos...

The oxidation of leachate coming from the composting of two organic wastes (wastewater sludge and organic fraction of municipal solid wastes) using the Fenton's reagent was studied using different ratios [Fe(2+)]/[COD](0) and maintaining a ratio [H(2)O(2)]/[COD](0) equal to 1. The optimal conditions for Fenton reaction were found at a ratio [Fe(2+)]/[COD](0) equal to 0.1. Both leachates were si...

This is a rather interesting and ingenious experi­ mental laboratory approach to handling the organic fraction of municipal solid waste. Since this organic fraction is the portion that is putrescible, it presents a special disposal problem. Once segregated, it might be usefully disposed in the manner sug­ gested. However, much separation and preparation are required to obtain the organic fracti...

The USA has significant experience in the field of municipal solid waste management. The hierarchy of methodologies for dealing with municipal solid wastes consists of recycling and composting, combustion with energy recovery (commonly called waste-to-energy) and landfilling. This paper focuses on waste-to-energy and especially its current status and benefits, with regard to GHG, dioxin and mer...
